13 Claims.

This invention relates to improvements in coin-controlled machines ofthe type in which a plurality of rotatable elements, such aslegendbearing reels, are adapted to be rotated and brought to rest inposition to display various combinations of legends having certainsignificance, or, for example, telling fortunes and indicating a certainnumber of tokens or checks to be delivered to the operator, such checksbeing usable, if desired, for further operation of the machine. Thegeneral form of this spinning reel type of machine is well known in theart and is illustrated in a number of prior United States patents, amongwhich may be mentioned Patent No. 1,586,455.

In machines of the type mentioned the legendbearing reels are startedrotating through operation of a manually operable coin-controlledmechanism, and are brought to rest by stop devices which areindividualized to the reels, and which operate automatically to stop thereels in various positions so that upon successive operations of themachine different combinations of legends will be displayed throughwindows which are provided in the casing opposite restricted peripheralsections of the reels. The reel stop devices usually comprise arms orlevers which are adapted to be moved into engagement with toothed wheelson the reels to stop rotation of the reels after they have been allowedto spin for a predetermined length of time. The number of differentpositions in which any particular reel may be brought to rest thusdepends upon the number of teeth in the stop Wheel on the reel, eachtooth representing one position of rest.

An important object of the present invention is to provide means wherebythe number of positions in which the reels may be stopped for a givennumber of teeth on the reel stop wheels is increased through theprovision of adjusting mechanism for the automatic stop devices whichenables said devices to stop the reels in positions of one series for acertain adjustment of the stop devices and in positions of anotherseries for another adjustment of said devices.

Another object of the invention is to provide automatic adjustingmechanism for the stop devices which operates to effect a change in theadjustment of said devices, and hence a change in the series ofpositions in which the reels may be stopped, at regular intervals ofoperation, or after a predetermined number of operations, therebyminimizing the opportunity for frequent repetition of particularcombinations of legends.

Other objects and advantages of the invention will be apparent from thefollowing detailed description, taken in connection with theaccompanying drawings, wherein I have shown the preferred form in whichI have thus far contemchine which is provided with the improvedadjusting mechanism for the automatic stop devices;

The general construction of coin or check-controlled machines of thetype which employ a plurality of rotatable elements or reels which havelegends arranged around their peripheral surfaces to indicate points orscores, or tobe used in conjunction with vending mechanism which may beembodied in the machine, is well understood in the art, and I shall,therefore, describe the general structure of such a machine only insufficient detail to give an understanding of the nature of theimprovement which forms the subject matter of the present invention. Inthe embodiment shown, the apparatus includes three legend-bearing reelsll, l2 and [3 which are mounted for free rotation on a shaft M, thelatter being journaled at its opposite ends in frame uprights l5 (oneshown) which are carried by a base plate IS. The peripheral surfaces ofthe reels are marked with legends l6 which are of various configurationsand which may be viewed by the operator through a window l1 (Fig. 8)which is mounted in the upper front portion of the cabinet wall l8. Aswill presently more fully appear, the reels are stopped in such positionthat one of the legends l B on each reel will lie beneath the window I1so that the operator may thus view the combinations of legendscorretrated in Figs. 1 and 8. A rock shaft 25, which is journaled at itsopposite ends in the frame up:

rights I (see Fig. 2), carries a forwardly projecting arm 26 which ispivotally connected at 21 to the lower end of a link 28, the upper endof the latter being pivotally connected at 29 to an arm 3|, said arm 3|being pivoted at 32 to a fixed point on the frame. A pawl arm 33 ispivotally connected at 34 to the arm 3| and is normally held against thelatter by a coil spring 35, one end of which is connected to the arm 3|,the

other end of said spring being connected to the.

arm 33. A lug 36 carried on one-end of arm 33 engages over the edge ofarm 3|, thus serving as a stop to limit the relative movementbetweenthese parts. The free end of. pawl arm 33 carries a pawl 31 which isadapted to simultaneously engage shoulders 38 on all three of theratchet disks 22, 23 and 24. When rock shaft 25 is pivoted in aclockwise direction, viewing Fig. 8, pawl arm 33 and arm 3| are movedfrom the solid to the dotted. line position of said figure, the pawl 33riding upwardly over the teeth 38 and the arm 33 pivoting in acounterclockwise direction on arm 3|. The coin-controlled mechanism foractuating the main rock shaft 25 which is not illustrated in the presentdrawings, but which is fully shown a in U. S. Patent No. 1,586,455, isso arranged that after said shaft has been turned through a portion of arevolution, in a clockwise direction, viewing Fig. 8, it will besuddenly released and returned to normal position by springs 39 (Fig. 4)which extend between cams 4| on said shaft 25, and fixed points on baseHi. This sudden return movement of shaft 25 pulls pawl arm 33 downwardlyagainst the teeth 38 on the ratchet disks with a quick snapping actionwhich rotates the disks and the reels connected therewith in acounterclockwise direction, viewing Fig. 8.

Mechanism which is operated from rock' shaft 25 is provided for bringingthe reels to rest in positions which will display various combinationsof the legends l6. Referring particularly to Fig. 4, each reel isprovided with a stop lever 42 which is fulcrumed on a cross shaft 43,the latter extending between frame upright l5 and a frame bracket 44.The stop levers 42 are providedwith sections 45 which are movablysupported on said levers by pins 46 which are received in slots 47, itbeing noted that for the upper connection the pins 46 are carried bylevers 42 and extend through slots 41 in the sections 45, while for thelower connection the pins 48 are carried by the movable sections 45,being clamped thereto by shouldered studs 50, and the latter projectingthrough slots 41 formed in levers 42. The purpose of this: movableconnection between the levers proper and the movable sections supportedthereon will more fully hereinafter appear. The upper ends of saidmovable lever sections 45 are provided with stop lugs 48 which, as shownin Figs. 5 and 6, are adapted to engage the teeth 49 on the reel starwheels. When the reels are at rest stop levers 42 are either in theposition shownin Fig. 5 or in the position shown shown in Fig. 4, thismovement of. the cams 4| serving to pivot levers 42 to the positionshown in Fig. 4, thus freeing the sections 45 from the star wheels.

The stop levers 42, after being moved to the position shown in. Fig. 4,are adapted to be progressively released so that they may be projectedinto reel stopping position by the springs 52. The mechanism foreffecting this release is best shown in Figs. 2, 3 and 4. A clock arm53, having three forwardly extending projections 54, is pivotallyconnected at one end to a frame piece 55, the pivotal connection betweenthese parts being indicated at 56. When the reels are at rest this armis positioned as shown in Fig. 3. When rock shaft 25 is turned to startspinning of the reels said arm 53 is adapted to be moved forwardly tocarry the projections 54 beneath rearwardly projecting arms or footportions 5'1 which are formed on the lower ends of stop levers 42. Itwill be recalled that during the wind-up operation levers 42 have beenraised to the position of Fig. 4, so that foot portions 51 will clearthe extensions 54 on the clock arm. In Fig. 4 one of the extensions 54on the clock arm is shown positioned beneath one of the arms 51, inwhich position it will be apparent that the clock arm 53 and theprojection 54 thereon serve to hold the stop lever out of engagementwith the reel star wheel.

The mechanism for advancing clock arm 53 into position to hold the stoplevers in inoperative position comprises; a crank arm 58 (Fig. 2) whichis rigid on rock shaft 25; a bell crank 59, fixedly secured to a shaft6| which is journaled in a frame plate 62; and a link 63 which ispivoted at 64 to one arm of bell crank 59, the other end of said linkbeing pivoted at 65 to clock arm. 53. When the rock shaft is turned in acounterclockwise direction, viewing Fig. 2, arm 58 moves against a lug66 on bell crank 59 to pivot the latter in a counterclockwise direction,viewing Fig. 3, which movement, in turn, moves link 63 and clock arm 53to the right to carry the projections 54 beneath the foot portions; 5'!of the stop levers. This movement of the parts is resisted by a coilspring 61, which extends between bell crank 59 and the frame, and alsoby a second coil spring 68, which extends between clock arm 53 and theframe. After rock shaft 25 has been.

released the springs 61 and 68 return the parts to the normal positionof Fig. 3, this return movement being retarded by a vane 59 which isconnected through a clock gear train H to the shaft 6|, to which bellcrank 59 is secured. During this return movement of the clock arm thefoot portions 5'5 of the reel stop levers are dropped progressively fromthe extensions 54, whereupon they are projected against the reel starWheels to arrest rotation of. the reels. It will be noted from Fig. 3that the projections 54 are of various lengths so that the stop leverswill be released in predetermined order. g

It will be noted from Figs. 4-6 that the reel star wheels l9-2l are eachprovided with ten teeth. With the usual form of stop lever which hasheretofore been commonly employed in these machines, the construction issuch that the point of engagement of the lugs 48 with the teeth 49 isfixed so that there is but one position of rest of the reel for eachtooth on the star wheel. In some instances the reels are provided with agreater number of legends than there are teeth on the star wheels, sothat it might appear to the player that there are a much larger numberof legends which could be displayed than could possibly be displayedbecause of the limited number of stop positions which are permitted bythe star wheels. In accordance with my invention, the reel stop levers42 are made adjustable in length through the provision of the movablesections 45, and mechanism is further provided for automaticallyadjusting the lengths of the levers on predetermined operations of themachine, thereby providing a greater number of possible positions ofrest for a given number of teeth on the reel star wheels. The principleinvolved will be understood by reference to Figs. 5 and 6. In Fig. 6 thelever section 45 is in the extended position, the pins 46 being at theupper ends of the slots 47. It will be noted that in this extendedposition the tooth 49 which is engaged by the stop lug 48 is but aslight distance below the center of the reel shaft l4. This representsone of a series of positions in which the reels may be stopped by thelevers 42. In Fig. 5 the lever sections 45 are in the retracted orshortened position, the pins 45 being at the lower ends of the slots 41.It will be noted that in this position the tooth 49 on the star wheelwhich is engaged by the stop lug 48 is considerably below the center ofshaft l4. This represents one of a second series of positions in whichthe reels may be stopped, this series being obviously different from theseries of positions in which the reels will be stopped with the leversin the extended position of Fig. 6. In the embodiment shown each reel isprovided with twenty of the legends 16, that is, twice the number ofteeth on the star wheels. Any one of ten alternate legends on each reel,representing one series of stop positions, may thus be brought to restopposite the window I! when the stop arms are in the shortened positionof Fig. 5, and similarly any one of the remaining ten alternatelypositioned legends, representing the second series of stop positions,may be brought to rest opposite the window I! when the levers are in theextended position of Fig. -6. It will be understood, of course, that inreferring to series of positions I mean that for one adjusted positionof its stop lever a reel may be brought to rest in any one of the tenpositions of that series.

The mechanism which is provided for automatically adjusting the movablelever sections 45 is best shown in Figs. 2-4. Each stop lever isprovided with an arm 12 which has associated therewith its lower end oncross shaft 43. The upper end of said arm is formed to provide a camsurface consisting of a rather steeply inclined portion 73 and a more orless straight portion 14, the lat ter terminating at the tip end of thearm in a stop lug 15. This cam surface formed on the upper end of thearm 12 engages under the stud 59 which projects from the lower pin 46through the lever 42. In Fig. 5 the portion 13 of the cam surfaceengages stud and allows the movable lever section 45 to drop to theshortened position. In Fig. 6 the portion I4 of the cam surface engagessaid stud 50 and holds the lever section 45 in the extended position.

The adjustment of lever sections 45 from the position of Fig. 5 to theposition of Fig. 6, and vice verse, is accomplished automatically, andupon predetermined operations of the machine, by cam mechanism which isoperated from rock shaft 25. In the embodiment shown this mechanismcomprises: a cam 15 which is journaled on the shank of a. bolt ll, saidbolt being secured in a wall section 18 of the frame; a tie rod 19 whichextends between rearwardly extending projections 8| formed on arms 12,the opposite ends of said rod being threaded to receive lock nuts 82(Fig. 3),

and the portions of said rod lying between the l projections 3| beingprovided with spacing sleeves 83; a push bar 84 which is pivoted at 85to link 63, the forward end of said bar being shaped to provide a pawl85 which is adapted to engage pins 87 carried by cam '16; a guide plate88, secured to the wall section 18, and having an inturned flange 89which is slotted to receive the forward end of push bar 84; and a springstrip 9| which is secured to the outer surface of the Wall section 18,the forward end thereof being bent inwardly (Fig. 3) to engage behindthe pins 81 on cam 16.

Referring particularly to Figs. 1-3, the end portion 92 of tie rod 79rests on cam 16. In the embodiment shown, this cam is shaped to provideoppositely disposed concave surfaces 93 which are separated byoppositely disposed convex surfaces 574. When the end 92 of tie rod 19is resting on one of the convex surfaces 94, as shown in Figs. 4 and 6,the arms 12 will be held in such position that the cam surfaces 14 willengage the stud 58 of the movable stop arm sections 45, the latter beingthus held in the extended position of Figs. 4 and 6. When the cam 16 isturned so that said end portion 92 of rod 83 rests on one of the concavesurfaces 93, as shown in Fig. 5, arms 12 will be held in such positionthat the cam surfaces 13 engage studs 58, thus allowing the movable stoparm section 45 to assume the shortened position of Fig. 5. Upon eachoperation of the machine cam 16 is adapted to be turned through aquarter of a revolution in a clockwise direction, viewing Fig. 4,thereby changing the lengths of the reel stop arms each time the machineis operated. This cam is turned by push bar 84 which, being actuatedfrom link 63 which also operates the clock arm 53, is moved forwardlyfrom the positions of Figs. 2 and 3 at the time said clock arm 53 isadvanced to carry the projections 54 beneath the stop lever foot members57. As the push bar 84 moves forwardly from the position of Fig. 2, thepawl 86 thereon strikes one of the pins Bl, continued advance movementof said bar turning cam iii through a quarter of a revolution or untilthe pin 8"! which is engaged by pawl 86 moves past the forward end ofthe spring strip SI, whereupon the latter snaps behind the pin to holdthe cam against return movement. Upon return movement of clock arm 53and link 63, push bar 84 is retracted to assume the position of Fig. 2,the edge portion 95 thereof falling against the next succeeding cam pin81 to position the bar for the next stroke. It is thus apparent that cam16 is operated in timed relation with the automatic stop devices, andupon each operation effects a change in the lengths of stop levers 42 soas to change the series of positions in which the reels are stopped. Itmay be added that the cam 16 is rotatably supported on the bolt 11through the medium of a sleeve 96 (Fig. 7) which Gil is anchored in thehub portion of said cam." A coil spring 91 disposed between the cam andwall section 18 holds the cam in yielding engagement with the head ofbolt 11. V

The invention not only accomplishes the result of providing a largernumber of positions in which the reels may be stopped for a given numberof teeth on the reel star wheels, but also has the effect of preventingfrequent repetition in the display of the same combinations of legends.In the embodiment illustrated in the drawings,

the lengths of the stop levers 42 are changed; upon each operation ofrock shaft 25. It follows from this that upon each operation of themachine there will be a change in the series of positions in which thereels may be stopped. This minimizes the tendency for the repetition ofthe same combination of legends upon successive plays. It is obviousthat the frequency with which the lengths of the reel stop levers ischanged depends upon the shape of the cam 16.

If desired, this cam may be so shaped thatithe stood therefrom, but theappended claims should be construed as broadly as permissible in view ofthe prior art.
